What happens after getting placed?

My question is a hypothetical one.If we get placed through elitmus ,then are we eligible to apply any further and will elitmus consider our candidature for upcoming jobs?not placed btw still waiting its been 3 days already

Yes. If you check job listing, there are many job which are for experienced candidates.

If you join the company, then Elitmus stops you from applying further. Before that you can apply.
